How Does it Work?

Our Zero-Bill Process is designed to eliminate your electricity costs with precision and certainty. We analyse your energy habits, engineer a custom solar + battery system, and guarantee zero bills for 10 years—backed by fair usage, expert installation, and full reimbursement if needed.

  • We start by studying your home’s complete energy habits:

    • Past electricity bills

    • Daily and seasonal usage patterns

    • Household size and lifestyle

    • Future needs and expected changes

    We don’t guess — we model exactly what it will take to eliminate your electricity bill long-term.

  • Using your energy profile, we design a custom solar + battery system built to cover 100% of your power needs, day and night.

    Every system is premium-grade and installed by our in-house Black Diamond Solar experts —
    no outsourcing, no compromises.

  • Once your system is installed, your home is placed into the Black Diamond Zero-Bill Program, where your outcome is guaranteed:

    • No electricity costs for 10 years.

    • If you get an electricity bill during that decade, we pay it — not you.

  • If you receive a payable electricity bill within 10 years:

    1. Send us the bill within 7 days, and

    2. We reimburse the full amount.
      Simple, fast, and guaranteed.

  • Your system is engineered with 50% extra usage capacity to give you freedom and flexibility.
    We cover up to 50% usage above the original agreed amount.
    Nothing hidden — just fair and transparent.

  • To achieve a true $0 electricity bill, we handle the retailer side too.

    • We nominate the most suitable energy retailer for your home.

    • We negotiate premium rates on your behalf.

    • If we recommend a switch, you’ll need to move to that retailer within 14 days.
      We’ll notify you with clear instructions — no stress, no hassle.

  • Solar energy is generally cheaper due to a combination of declining costs in technology and increased efficiency in solar panels. The price of photovoltaic cells has significantly fallen over the past decade, making solar installations more accessible for homeowners and businesses alike. Additionally, the long-term savings on electricity bills can offset the initial investment, while government incentives and tax credits can further reduce upfront costs. As solar technology continues to advance, the overall financial viability of solar energy becomes

  • Solar energy works by harnessing sunlight and converting it into electricity through the use of photovoltaic (PV) cells, which are often found in solar panels. When sunlight strikes these cells, it excites electrons within the material, creating an electric current. This process begins with the absorption of photons from sunlight, which then generates electron-hole pairs in the semiconductor material of the PV cells. The movement of these electrons creates direct current (DC) electricity, which can be converted into alternating current (AC) electricity using an inverter, making it suitable for household use. The electricity produced can either be used immediately, stored in batteries for later use, or fed back into the grid, contributing to the overall energy

  • The cost of installing solar energy systems can vary significantly depending on several factors, including the size of the system, the type of technology used, and the specific installation requirements. On average, homeowners in Australia can expect to pay between $4,000 to $8,000 for a standard solar panel installation. This price generally includes the cost of the panels, inverter, mounting equipment, and installation labour. Additionally, there may be ongoing maintenance costs and potential incentives or grants that can impact the overall financial outlay. Despite the initial investment, many homeowners find that solar energy provides long-term savings on electricity bills and contributes to sustainable energy solutions.
